Step-by-step explanation:
Danny would likely need to use 8 Trading Power to book a 4-night hotel stay and save. Trading Power is a measure of the value of a timeshare unit and is used by exchange companies to determine the value of a timeshare week or unit.
In this case, each night of the hotel stay would require 2 Trading Power, so for 4 nights, Danny would need to use 8 Trading Power in total.
